2. Grind the graham crackers to coarse crumbs in a food processor or with a rolling pin and a resealable plastic bag. Add the butter and sugar and process or stir until the crumb mixture is well blended and begins to stick together.

3. Press the crumb mixture onto the bottom (but not the sides) of a 9-inch-diameter spring-form pan with 2 3/4-inch-high sides. Bake the crust until golden and firm to touch, about 25 minutes. Cool the crust in the pan on the rack. Wrap the outside of the pan with 3 layers of heavy-duty foil. Keep the oven at 325°F (163°C).

Make the filling

4. While the crust bakes, beat the cream cheese in a large bowl with an electric mixer on medium-high speed until fluffy. Gradually add the sugar and beat until blended.

5. Beat in the eggs, one at a time, mixing just until just blended after each addition. Then add the egg yolk, scraping down sides of bowl. Beat in the lemon juice, vanilla, and salt. Sift the flour over the filling and beat on low speed just until blended. Scrape the filling over the cooled crumb crust.

6. Place the foil-wrapped cake pan in a large roasting pan. Place the roasting pan on the oven rack, pulling the rack out slightly. Carefully add enough hot water to the roasting pan to come halfway up the sides of the cake pan. Bake the cheesecake in the water bath, rotating the pan once halfway through, until the center is softly set, about 1 hour and 15 minutes. Remove the roasting pan from the oven.

7. Let the cake pan stand in the water bath for 5 minutes. Remove the cake pan from the water bath and transfer it to a wire rack. Using a sharp, slender knife, work around the sides of the pan to loosen the cake. Cool completely at room temperature. Cover and—here’s the hard part—refrigerate overnight or for up to 2 days prior to slicing.
